# Installation

> Install the hexel CLI for infrastructure and resource management.

The `hexel` CLI manages Hexel Studio infrastructure from the terminal: compute, fleets, tasks, tools, policies, approvals, runtime, and auth.

## Install

```bash theme={"dark"}
curl -fsSL https://hexelstudio.com/install.sh | bash
```

Or build from source (requires Go 1.22+):

```bash theme={"dark"}
go install github.com/hexelstudio/cli@latest
```

## Authenticate

```bash theme={"dark"}
# API key
export HEXEL_API_KEY="YOUR_API_KEY"

# Or OAuth client credentials
export HEXEL_CLIENT_ID="YOUR_CLIENT_ID"
export HEXEL_CLIENT_SECRET="YOUR_CLIENT_SECRET"

# Verify
hexel auth login
```

Per-command flags `--api-key`, `--client-id`, and `--client-secret` are also available.

## Global flags
